 # github-zen: A tiny utility for reading github zen
 A tiny piece of javascript for watching zen streaming from GitHub API
 
-## Installation
-
 - Install node.js;
 - Clone the repo;
 - ```$ npm install```;
 - ```$ ./zen.js```; 
 - Watch it.
+
+### Tips and tricks
+Default API limit is 60 requests per hour. You can enlarge it by passing your **GitHub** username as a first parameter.
+
+You can also redirect output to a file so that you can read it later:
+```
+$ ./zen.js > zen.txt
+```
